The results of multivariate logistic regression analysis showed that education degree(OR=0. 148)、 times of pregnancy(OR=3.372)、 history of induced bortion (OR=Z. 617) had association with hydatidiform mole.

经多因素分析调整后,文化程度(OR=0．148)、妊娠次数(OR=3．372)、人工流产史(OR=3．617)与葡萄胎的发生仍呈相关关系。

Conclusion This research suggested that Education degree、 times of pregnancy and history of induced abortion were identified as having important effect on hydatidiform mole.

26 patients with thymic masses were operated upon from 1961 to 1977 in Capital Hospital. There were 24 cases of thymoma.Ⅰeyst and Ⅰhypertrophy, Ⅱcases (42%) were clinically-pathologically malignant, 1/3 of the patients had mysthenia gravis, and in 1/6 cases leukemia, erythema nodosa. Meniere's syndrome or pregnancy co-existed. Excision was done in 21 patients. Among the 11 malignant thymomas exploratory thoracotomy and biopsy were done in 5 pstients, complete extirpation was perfomed in 4 patients, and...

26 patients with thymic masses were operated upon from 1961 to 1977 in Capital Hospital. There were 24 cases of thymoma.Ⅰeyst and Ⅰhypertrophy, Ⅱcases (42%) were clinically-pathologically malignant, 1/3 of the patients had mysthenia gravis, and in 1/6 cases leukemia, erythema nodosa. Meniere's syndrome or pregnancy co-existed. Excision was done in 21 patients. Among the 11 malignant thymomas exploratory thoracotomy and biopsy were done in 5 pstients, complete extirpation was perfomed in 4 patients, and in 2 patients only palliative excision was possible. Pathological examination showed no specific correlation between the tumor size and malignancy, nor do the histological characteristics with myasthenia gravis, but lymphocytetype thymoma seemed to have a better prognosis.

15 cases of thymectomy for myasthenia gravis were reported. There were 2 postoperative deaths in crisis and 13 survivals. The duration of follow-up ranged from 2 to 13 years, 20% of 13 cases have had marked improvement and 67% of them complete remission. There were 3 cases of normal pregnancy and delivery. The therapeutic effects were affected by different histological types and completeness of surgical removal of the thymus. A median sternotomy was preferred. Prophylactic tracheotomy and routine assisted...

The duration of follow-up ranged from 2 to 13 years, 20% of 13 cases have had marked improvement and 67% of them complete remission. There were 3 cases of normal pregnancy and delivery. The therapeutic effects were affected by different histological types and completeness of surgical removal of the thymus. A median sternotomy was preferred. Prophylactic tracheotomy and routine assisted respiration were not necessary.The importance of eliminating predisposing factors, parenteral prostigmine and sufficient ventilation in the prevention and the treatment of crisis was emphasized.

Here we report 19 cases of artificial insemination from Dec. 1983 to Feb. 1985 with frozen stored donor semen. Semen samples were taken from suitable donors, frozen in vapor of liquid nitrogen and stored in liquid nitrogen with an improved method. The longest period of semen storage lasted 12 months. Sperms appeared to suffer no significant loss in cryosurvival rate. To evaluate the optimal time for insemination we used the history of menstrual cycles, basal body temperature and cervical score as the clinical...

Here we report 19 cases of artificial insemination from Dec. 1983 to Feb. 1985 with frozen stored donor semen. Semen samples were taken from suitable donors, frozen in vapor of liquid nitrogen and stored in liquid nitrogen with an improved method. The longest period of semen storage lasted 12 months. Sperms appeared to suffer no significant loss in cryosurvival rate. To evaluate the optimal time for insemination we used the history of menstrual cycles, basal body temperature and cervical score as the clinical parameters. The maximal possible cumulative cervical score was 15. It is supposed that ovulation would take place when cumulative cervical score was≥10. Insemination was carried out in 3-4 successive days. 13 women were fertilized. Fifteen pregnancies occurred in 27 treatment cycles. 10 of the 15 pregnancies occurred by the first treatment cycle and 5 the second treatment cycle, Mean number of cycles per conception was 1.8. There were 2 miscarriages and 7 live births, others are still in gestation.
